Glass fiber
- Apr 08, 2018 -

Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has many advantages, such as good insulation, high heat resistance, good corrosion resistance and high mechanical strength. However, its disadvantage is brittleness and poor wear resistance. It is made of glass balls or waste glass made of high-temperature melting, drawing, rewinding, weaving, etc. The diameter of its monofilament is several micrometers to 20 micrometers, which is equivalent to a hair. For 1/20-1/5, each fiber bundle consists of hundreds or even thousands of monofilaments. Glass fiber is generally used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other various aspects of the national economy.

On October 27, 2017, the International Agency for Research on Cancer (IARC) of the World Health Organization published an initial review of the list of carcinogens. Special-purpose fibers, such as E-glass and '475' glass fibers, were listed in category 2B carcinogens. Continuous glass fibers were Category 3 Carcinogen List
